Specification of Letters Patent.

Patented Feb. e, 1909.

Application filed. March 28,v 1908. SerialNo. 423,853.v

To all whom it may concern: l

Be it known that I, JAivfnsV W.l Rensen citizen' of the United States, residing at Suisun,v in the county of Solano and Statezof Californiahave invented new and useful Improvements in Car-Doors, of which the .fol-

owing is a speciiication. j

My invention vrelates to improvements in car doors, and is especially designed ,for the In the usual construction of such doors, a

timber frame-work is made, and the boards forming the' door are secured upon this frameework, leaving the timbers. on the interior exposed sothat if boxes or goods happen to fall against them, they will often prevent the opening of the doors. Such doors as ordinarily constructed are liable to bind so, as not to be' readily opened when they are pushed for the purposeN of sliding them, when opening; and lastly, in the ordinary construction of doors, very 'considerable spaces appear through which dust and dirt, and sometimes sparks may enter the car, to the great damage of delicate goods that may be 'contained therein.

It is the object ofmy invention to overcome these difficulties, and to provide a door that is smooth on both surfaces, to 4properly hang and balance the 'door so that it will always run easily in opening and closing, and

to provide such closures as will prevent the entrance of dust into the car. c

In the drawings, I have only shown. so much of the car and connected parts as will enable me to explain my invention. x A shows the sideof the car, and B represents a portion ofthe car floor.

The door is made 'of sufficiently heavy jointed togetherand form the inner face.

pon this inner structure are secured` the vvertical boards, the whole being strongly secured together,l and forming a. door whlch is smooth upon both sides.

To theside of the car above the door opening is fixed a metal trough 4, and in the up er part of thistrough is iixeda' strip of Wood 5y running the length of thetrough; the strip of 'woodand the trough being bolted tolgether and to the car.

The bottom is formed by bending the sides at `right angles, and these form a support for the rollers, with a channel between for the passage of the hanger hereafter described.

a 6 are rollers mounted upon axles 7 which are iixedin hangers'S. te'nd downwardly through the above mentioned slot, and may be let into the material .of the doors substantially central between the outer andl inner sides thereof, and they are firmly bolted or otherwisesecured thereto, as shown at Q. This construction causes the.' door to be evenly' balanced, and the rollers travel upon the inturned anges of the trough.

` 4a Ais a sheet of rolled steel bolted on the l'outside of Y'the'trough and extending dpwn outside the door to cover the space between the upper ed e of the door and the trough These hangers exto prevent t edentranceV of dust, rain or sparks. The door closes iiush against the door-frame 13.

10 is an angle ironl trough bolted to the side of the car just belowv the floor, andthe -inner portion 2 of the door extends downwardly into this trough as shown.

11 is a strip of 'half round iron which is i'xed on the outside of this extended portion of the door; and if any pressure be brought upon the door from the inside, this strip will be pressed against theinner portienmf the trough 10, making a .comparatively small bearing, and allowing the door to be moved more easily. l

The outer art '3 of the door extends down to just a ove thetop of the trough 10, and it projects sufliciently beyond the edge of the trough to divert any water from rains or otherwise, and discharge it outside the trough. p. y

12'is a stripof rOnfaStened to the'eige ofthe door, extending the full length thereof, and its lower end is ,bent to lan angle as shown, so that `when the door is closed, it overlaps the lower end of the ytrough and door-frame, and prevents dust, water or sparks from entermg.

A door lo'nstructed in this manner may be easily opened and' closed, since it is not subject to being locked from the pressurelvof oxes against .the inside;vv the smooth surface allowing it te be moved without the use of envvbars or other Ineans for forcible entry. Such a door will last for many years with feW repairs. The manner in which the door is hung, coupled With the Wheels and trough upon which it yrolls,is also a special feature;

'unnecessary' as the trough, itself, fornis a hood. The troughs, top and bottom, forni practically seals to prevent dust freni enterlng the oar, and the bottom trough forming a guide for the door, will prevent its flying out so as to strike ears on sidingsor passing on vother tracks.

Having thus described my invention, what I claim and desire to secure by Letters atent is- I 1. The combination ina ear having a side door opening, of a rectangular channel iron trough with inturned lower edges fixed herizontally above the door opening, and having an exterior downwardly extending lip, a eorres ending trough with up'turned flange fixed i elow the door opening, a door formed of transversely secured boards, the interior layer of which extends below 'the exterior layer and the ear floor, and enters the lower trough, and the upper edge of the door extending Within the upper li hangers fixed centrally between the door llayers, and extending upwardly into the upper trough, Wheel shafts fixed transversely to the hangers, and wheels journaled thereon on eaeh side of the hangers, and supported on the inturned flanges of the trough.

2. In a ear door opening closure of the character described, a smooth-surfaced double layer door, with hangers iixed centrally between. the la Ters a horizontal reetanffui lar open-bottomed trough 'lixed above the door-opening having a depending lip, into which trough the hangers project, Wheels journaled on opposite sides of the hangers, and supported on the trough bottoni, an angular open top trough fixed below Vthe door opening, into which the lower interior layer of the door extends, and which the exterior overlaps, and a strip of iron fixed to the Vertical edge of the door, and having an angular bend at the bottoni to engage and overlap `the end of the trough when the door is Closed.

In testirlrony whereof I have hereunto set my hand in presence of' two subscribing Witnesses JAMES W. RUMSEY.
